| Functionalized 3D glass-ceramic membranes for advanced photocatalytic drinking water treatment | |
| Program: | SRDA |
| Project leader: | Ing. Michálková Monika, PhD. |
| Annotation: | Micro-pollutants, such as medication, disinfectants, laundry detergents, pesticides, metals, and antibiotic-resistant organisms, can often be found in underground and drinking water. To remove these pollutants, a specialized filtration process with effective porosity in the micro or nano range is required. Membrane processes offer numerous benefits over traditional water treatment methods, including high efficiency, low energy consumption, small space requirements, and environmental friendliness. However, membrane processes can also face challenges, such as scaling, fouling, and degradation, which can negatively impact their performance and lifespan. Efficient and affordable water treatment technologies are critical in today\’s world. The proposed project seeks to create durable, highly porous photocatalytic glass-ceramic membranes supplying specific nano, micro, or macro needs. The project will employ innovative and cost-effective upcycling techniques of pharmaceutical non-recyclable waste glass and various 3D additive techniques to develop the next generation of membranes. Creating these advanced 3D porous structures requires using a suitable precursor with micro-level porosity. This will be achieved through the process of alkaline activation and flame synthesis of pharmaceutical glass frit. TiO2 and Fe2O3 will be added to the glass structure to give photocatalytic properties in the UV-VIS region. The design optimization of membranes will solve the macroporosity. After printing, the final step involves using microwave sintering to create the 3D membranes, which has a lower environmental impact than traditional sintering methods. Additionally, an advanced phase separation process will be applied to achieve porosity on the nano level. |

| Vývoj pokročilých luminiscenčných sklenených 3D štruktúr pomocou aditívnej výroby | |
| Development of advanced luminescent glass 3D structures by additive techniques | |
| Program: | VEGA |
| Project leader: | Ing. Michálková Monika, PhD. |
| Annotation: | The main goal of the project is to develop a new generation of luminescent phosphor-in-glass (PiG)optoelectronic materials with high efficiency, low-cost fabrication (3D printing), and tailored luminescenceproperties. Additive manufacturing will enable the combination of mutually supporting phosphors in differentlayers within a single glass matrix, thus improving the optical properties of the final material. In addition, thephosphors used for additive manufacturing will be prepared in spherical shapes – microspheres that can be solidor hollow – to further enhance the efficiency of the phosphor. |
